Does it matter if it is a layer of aluminium or copper in a 3 or 5 ply stainless steel pot?

Question

Why does it matter? Which of the 2 is safer for cooking despite being in between the stainless steel layers? Are there are other options? Which brand of pots would it be?

Answer 1

Both safe as it is sandwiched between stainless. Both these metals are placed in here for their heat conductivity. The copper would be my choice because it is the best for its conduction, if you want quick heating then copper all the time! The stainless makes the copper more durable and increases the life of the pans/pots. Stainless is a poor conductor by itself but is strong!

I do know that a brand of cookware called Esteele is about 5 ply with a copper core, off hand I cannot remember any others.

Answer 2

aluminium is very good for the price, copper is excellent, it is a better source of heat conductivity, but it is more costly. the thicker and more layers the better.
